And for the record, I think that parts of the interface are the only thing that are VN-like. But even the general tone of the interface, and the fact that there are all these stats and combat-themed icons, is not VN-like at all. Also it isn't dripping with dialogue, and it has no romance or "sexy anime." I think the Smugglers series is a good example of something that isn't a VN, but sort of looks like one. It's really nothing like this game, either, but still. What we have is an immediate-first-impression problem, not a remotely-what-this-is problem.
Perhaps now my thoughts about showing no interface and the thing "You have died of dysentery... and robots" now makes more sense. Then show the game and show the text about the real hooks. It hopefully helps to overcome that first (incorrect) knee-jerk reaction.
